Peoria, Ill. (WMBD) — As the days get shorter, temperatures get cooler and the foliage begins to change colors, its a sign of the inevitable…winter is coming.

Okay, that was cheesy.

However, the changing seasons and cooler temperatures are a sign that winter and our first snow are only a few months away. There’s no way to know exactly when we’ll see that first snow, but by looking back at what has happened in the past, we can get a good idea as to when the first flakes might fly.

The odds are that most of Central Illinois will make another two and a half months before seeing the first measurable snow of the season and three months before we need to find those shovels. Here’s a look back at a number of stats for Central Illinois communities and what we see on average.
